FURNITURE SHOPS, INC., OF'CHICAGO, ILLINIS, A CORPORATIONOF' ILLINOIS nX'rnNsiBLn TABLE Application filed May 6, 1929. Serial No. 360,758.

The present invention relates to extensible tables, and is particularly concerned vvith tables having extensible sections adapted to f frame, but Which must be moved upward( relative to the table frameyto permit the extensions to slide out'into place, after Which the table top is dropped down level with the` extension. The necessity for simultaneously lifting, the table top and also moving the ex tensions beneath it, make such devices dii'licult to operate vwithout pinching the lingers or marringthe extensions, and one of the objects of the present invention is the elimination of the'foregoing diiliculties a-nd the provision of a table with extensions and guide mechanisml whereby the extensions may be automatically moved out and leveled With the table top, or the reverse, by merely applying force to the extension.

Another object is theprovision of an improved commercial form ofthe table shown in our prior application7 Serial No. 268,165, filed April 7, 1928, and an improved and simplified form of guiding mechanism forv extensible table tops.

Another object is the provision of a-n improved extensible table construction in which the extensions are providedv with means-for concealing the extension mechanism so that the extensible table may be constructed with the same attractive appearance accomplished in the case of tables not having extensions.

Another object is the provision of an extremely simple and sturdy slide mechanism for extensible tables or for other purposes, which embodies a minimum of moving parts and which may be manufactured at an extremely loW cost.

Other objects'and advantages of the invention Will be apparent from the following description and from the accompanying draw-y ings, in which similar ycharacters of reference indicate similar parts throughoutl the several views.

Referring toy Figs. 1 to, 3, 2O indicates the extensible tablein its-entirety, and-the tableis preferably provided with. a supportingframe indicated in its entirety at 21, a table top 22 fixedly supported upon the framey 21,` and one to permit the or more extensions or extensible sections 23 and 24 adapted to be located beneath the table top 22 as shown in Fig. 3, or automatically moved to the position shown in Fig. 1, where the extensions form a continuation of the table top.

The supporting frame 21 may consist of a plurality of transverse wooden frame members 25, 26, 27 and 28 joined to side frame members 29and 30,'the side frame membersV also being adapted to form aprons depending from the table top 23 and adapted to enclose the mechanism for guiding theextensions, as well as enclosing the extensions themselves when in the folded position. The transverse frame members 26 and 27 are located adjacent the top of the side frame'members 29 and 30, immediately below Vthe table top 22, thereby providing a support for a longitudinally extending frame member 31 secured to the frame members 26 and 27, preferably midway between the sides ofthe table and adapted to form a support for the guiding mechanism, and to act as a guide for frame members 32 and 33 carried by one of the extensions 24.'

As contrasted with the devices of the prior art, in which table extensions may be concealed beneath the table top, the table top 22 may be fixedly secured to the supporting framework 21, since the extensibleV sections 23 and 24 are connected to thev framework 21 with slide mechanism for automatically moving the sections out into extended position, without the necessity for lifting the top 22 sections to be moved out. It should be understood, however, that if desired, the top 22 may be made removable for other purposes. i

The supporting framework 21 may be provided with legs 34 and 35 of the extended pedestal type, as shown in Figs. 2 and 3, or if desired, the framework may be supported upon legs of any conventional type.

In the embodiment shown in Figs. 1 to 3, the extensible sections 23 and 24 are slightly narrower than the table top 22 so that the extensions 23 and 24 may be provided with depending aprons or side frame members 36 and 37 and an end frame member 38 of substantially the same appearance as the side frame members 29 and 30 carried by the top 22. Thus the side frame members 29 and 30 may extend the full length of the table top 22, and the extensions 23, 24 with their side frame members are adapted to be slidably received between the side frame members 29 and 30.

In the embodiments shown in Figs. 5 to 8, inclusive, the extensions 23 and 24 are made of substantially the same width asthe table top 22,'so that the extended table is substantially rectangular in form, but in such case, it is necessary to provide the side frame mem-V bers 29' and 30 with cutouts or slots as at 39Y extending from each end of the table toa point adjacent the transverse frame members 26 and 27.

In the latter embodiments, the extensible sections 23 and 24 need not be providedfwith the depending apron or side frame members 36,37 and 38, and the extension mechanism is concealed entirely, only when the extensions are in the folded position shown in Fig. 8. Y

Referring again to Figs. 1 to 3the longitudinal frame member 31 may be joined with the transverse frame member 25 by a verticall;7 extending frame member 40 and the longitudinal frame member 31 is adapted to provide a support for a pair yof guide plates 41and42.

The guide plates 41 and 42 comprise flat pieces ofsheet metal having laterally proj ecting lugs 43 or 44, and the guide plates 41, 42 are secured tothe frame member 31 by screws or other fastening means soV that the lugs 43, 44 project 'fromrthe opposite sides of theframe member 31.

The extension 24 vmay comprise a member of substantially the same thickness as, the table top 22 andadapted'to form a continuation thereof, and in the present embodiment, the extension 24 is provided with the side and end frame members 36, 37, 38, forming an apron for concealing the slide mechanism.

rIheextensiou 24 is fixedly secured to a pair of inwardly projecting frame members 32 and 33 extending at right angles to the edge of extension 24, which is to vbe located adjacent table top '22. The frame lmembers 32, 33 extend parallel to each other, and are spaced suliciently to slidably receive the frame member 31 of the table between the frame members 32 and 33.

The frame members 32 and 33 are formed i with offset end portions 45, A46, the offset between the main body portion 47 and 48 of the frame members 32 and 33 and the ends 45, 46 respectively, being'equal to the distance between the lower surface of the table top 22 and the lower surface of the frame members 26.

It will thus be observed that when the extensible section 24 is located in the position of Figs. 1 and 2, the offsetends 45, 46 of frame members 32, 33 engage below the transverse frame members 26 when the upper surface of the frame members 32, 33 adjacent the edge 49 of section 24 engages just below the table top The upper surfaces of the frame members 32, 33 engaging beneath the table top 22, automatically level the section 24 with thetable top 22, the section being ica llo'

supported by the sliding mechanism'indie cated in its entirety at 50, further to be described, and acting upon the lugs 43, 44 of' the guide plates 41, 42.

The frame members 32 and 33 are each provided with appropriate slide mechanism indicated in its entirety at 50 and illustrated in detail in Figs. 9 to 12, each of the slide mechanisms being adapted to engage one of the lugs 43, 44. For vthis purpose the frame members 32, 33 are cut out as at 51 to receive the slide mechanism 50, and the frame members 32, 33 are rabbeted as at 52 from the slide mechanism to their outer ends, to provide space for receiving the lugs 43, 44 when the extensible section 24 is moved to the position shown in Fig. 3. Referring to Figs. 9 to 12, the slide mechanism 5() is illustrated in detail, looking downward in Fig. 1 atthe frame member '33. VThe slide mechanism may consist of a hardened metal plate 53, the proportions shape of which depend principally upon the thickness of the table top and extensible sections. The plate 53 is preferably provided with a laterally-projecting inclined flange 54 adapted to act as a camming surface engaging the lug 44 in raising the extension 24 from a position immediately below the table top 22 to a position approximately level with the table top 22.

The guide plate 53 is also preferably'provided with a horizontally extending flange 55 adapted to provide a support for` the extensible section 25 by means of the lug 44 when the exten-sion is in the position of Fig. 2. The horizontal flange or shoulder 55 is preferably provided with. a slot 56, into which the lug 44 may slide when the extension 24 lhas reached its extended position immediately adjacent the table top, so as to give the extension a greater degree of stability in its extended position.

The guide plate 53 is also `provided with a stop flange 57 carried by plate 53 at'thelower end of the inclined flange 54 for definitely limiting the movement of' the. lug 44 rela.- tive to guide plate 53., and the guide plate 1s also provided with a movable member or guide lever 58 pivotally mounted upon a stud or rivet 59A carried by plate 53.

The flange or shoulder 55 is preferably provided with a beveled edge 60, and the pivoted lever 58 with a complementary beveled surface 61, so that when the parts are in the position of Fig. 11, the lug 44 may slide off the lower edge 62' of lever 58, below the lower surface 63 of flange 55, without any1 substantial jar or noise. At its opposite end from the beveled surface 61, the lever 58 is provided with a point 64 adapted to engage the flange 54 so as to cause the lug 44 to be vcammed from the flange 54 to the lower surface 62 of lever 58. The provision of a horizontal lug or plate 44 in conjunction with an inclined flange 54 as shown in Fig. .1.0, also enables the point 64 to properly guide the lug 44 from the flange 54 along the edge 62 of lever 58. i

The lever 58 is preferably shaped to make the end 65 heavier than the pointed end 64 so that the lever 58 is biased to the position shown in Figs. 9, 10 and 12. The end 65 of lever 68 may be forked as at 66 and provided with an upwardly extending leg 67 adapted to engage the flange. 54 when the beveled edge 61 engages bevel 6() of supporting flange 55. v

Referringv again to Figs. 1 to 3, the extensible section 23 is also provided with a pair of inwardly projecting frame: members 68 and 69, the frame members 68 and 69 being located adjacent the lateral edges of the extension 23 in order to prevent their-interference withthe frame members 32 andy 33, carried by extension 24, and in order to utilize the side frame members' 29 `and 30 or parts carried thereby, as guides for the frame members 68, 69.

The side frame members 29 and 30l may flxedly support an auxiliary transverse frame member 70 which is adapted to support a pair of upwardly projecting blocks 71 and 72 in spaced relation to the side frame members 29' and 30, t0. leave space for the apron 36, 37 of the extension 23. The blocks 7l, 72 are provided upon their upper surface with guide plates 73 of substantially the form shown in- F ig. 4, secured thereto by a plurality of wood screws and provided with laterally projecting 'lugs' 74, 75. The laterally projecting lugs 74, 75 are adapted to cooperate with slide mechanism 50 carried by each of the frame members 68, 69 in substantially the same'manner as for that previously described for the other end of the table, with the exception that the slide mechanism 50 in the right end' of the table faces outward'to engage in-wardliyprojecting lugs 7 4, 75, while at the left end ofthe table, the slide mechanism faces inward to engage outwardly projecting lugs 43', 44.

The side frame members. 29" and 30Y are preferably provided with :blocks 76,` 77 located adjacent the transverse frame member 27 and the transverse frame member 27 may be provided with a pair of downwardly projecting dowel pins 78,. 79 adaptedto act as guides for the innerA ends of. the frame members 68, 69. The inner ends V80 and 81 of the frame members 6.8, 69 are offset-vertically from the body portion. of said;v frame members adjacent the extension 23, in substantially the same manner as described relative to the frame members-32, 33.

The transverse frame member 28 may be in Figs. 5 to 8, the construction and principle of operation of this embodiment is substantially the same, with the exception` that the extensions 23, 24 are not provided'with depending aprons, andvconsequently the extensions 23, 24 may be made of the same width as the table top 22, being adapted to be received within the opening 39 between the framework 21 and they-table top 22 at each end of the table. v y

In this embodiment, the framework of the table may beconsiderably simplified and the framework 2l may be provided at each end with transverse aprons or `frame members 85, 86 havingslots 87, Y88 for slidably receiving the frame members 32, 33 and 68, 69, respectively.

vVhen the embodiment of Figs. 5 to 8 is in the folded position of Fig. 7, the ends of frame members 32, 33, 68, 69 arepreferably located Hush with the end frame members 85, 86, and the table looks substantially like non-extensible tables, except that the top of the table appears to be of double thickness.

In order t-o fill in the space between the extensible sections 23, 24 at the side edge of the table when they areY in' the folded position of Fig. 7, an auxiliary strip of material 89 may be placed beneathcthe table top 22 at its outer edge, extending from the frame member 26 to frame member 27 so that the strip 89 lies flush with the extensions 23, 24 when they are in theY folded position shown in Figs. 7 and 8. Each of the extensions23, 24 in this embodiment is also provided with finger openings 90 centrally located in the lower surface of the extensions 23, 24, adjacent each end.

It should also be noted that in the embodiment of Figs. l to 3, the side frame members or aprons 36, 37 carried by the extensions 23, 24, are spaced slightly from the outer edges 91 of the extensions, leaving a shoulder 92 below the extensions immediately adjacent the frame members 36, 37. The side frame members 29 and 30-of the table frame 21 are rabbeted at 93 from the frame members 26 and 27, respectively, to the ends of the frame members-29 and 30. The rabbeted portion 93 of the frame members 29 and 30, forms a shoulder for slidably engaging beneath the outer edges 92 of the extensions 23 and 24 for supporting the extensions in folded position beneath the table top 22.

The operation of the extensible table is as follows.

When the parts of the table of Figs.v Lto 3 are in the position of Fig. 3, with the extensions folded, each extension is supported beneath the table -upon the shoulders 93 formed by rabbeting-the-side frame members 29 and 30 of the table frame 2l. The weight of the extensions 23 and 24 is generally such that the inwardly projecting frame members 32, 33, 68, 69 do not overbalancejthe extensions, sogthat the extensions may be supported'at their edges 92 upon the shoulders 93, without engagement of the extensions with the lower side of the table top 22. Either extension Vmay then be moved to the position shown in Fig. 2, by merely applying force to the extension at the finger opening. 84, VVthe operator pulling outward upon the extension23; c

For example, when a pull is exerted upon the extension` 23 at the finger opening 84, the extension 23 may be slid outwardhori- Zontally toa point slightly beyond the final position4 of the extension 23. During this motion, the extension` 23 is slidably supported upon the shoulders 93 of thetable frame and by engagement of the frame members 68, 69 in the base ofthe slots 82, 83. When the extension 23 is extended far enough, it is slidably supported ongthe table Aframe 21 by frame members 68,y 69,- the lugs 74, of the vslide mechanism progressing on the grooves provided by therabbets 52 in frame members 68, 69.

'Referring to Fig. 9, the slide; mechanism for automatically lifting the extensions is here shown in an intermediatel position, just after the extension has been slid out beyond its final position, but still in a position substantially parallel with the position shown in Fig. 3. The lugs 7 4;, 7 5 which correspond to lug 44 in Fig. 9, are thenina position of Fig. 9, and further horizontal motion of the extension 23, by pulling at the finger opening 84, will cause theflugs on the frame to engage beneath the inclined flanges 54 of the slide mechanism 50, the extension being lifted relative to the frame until the lugs reach the position shown in Fig. l0, where they engage the stop flanges 57. l

During thisk movement, the Vlugs 74, 75 have passed the pointed end 64 of the lever 58 and on release "of the extension, the lues 7 4, 75 will slide back against the lower side 'of the point 64 on lever 58 to retain the extension in this extended position.

rI`he extension is now substantially level with the table top, but is spaced therefrom and may be moved into the final extended position immediately adjacent the table top, by pushing inward on the extension 23, during which the mechanism operates as follows.

The lugs74, 75, corresponding to lug 44 in Fig. 10, are fixed relative to the table top and the lever 58 slides over1 lugs 74, 75, slightly lifting the extension until the lugs 7 4, 75 are directly beneath the pivot post 59, after which the weight of the extension causes the lever 58 to pivot counter-clockwise from the position of Fig.` 10 to the position of Fig. 1l.

The levery 58 is thus moved until its beveled ends 61 engage bevel 60 on iange 55, and the continued inward movement of the extension 23 causesthe lever 58 and flange 63 to slide smoothly over the 4lugs 74:,` 75, (correspending to lug 44 of Fig. 11) until'the lugs 74, .75 are finally seated in recess 56, which takes place when the extension V23 engages the edge of table top 22.

It should be understood Vthat some embodiments of the invention need not ybe provided with the recess 56 for finally determining the position of the extension, but such a recess is advantageous since the lugs 7e', 75 may drop into the recesses 56 to retain the extension in its proper position...

The extension 23 is thus supported in extended position by the engagement of the lugs 74, 75 in recesses 56 and at the same time the offset ends 80, 8l of the frame members 68, 69 are engaged beneath the frame member 27, Ythe frame members 68, 69 acting as cantilevers for supporting the extension 28.

When it is desired to fold the extensible table, that is, to move the extensions from the extended position to the positionshown in Fig. 3, it is necessary only to pull upon the extension 23, as at the point k84, in which case the curved recess 56 cams up over the lugs' 74, 75,` and the iange slides outward oif` the lugs 74:, 75.

Since the lever 58 is naturally maintained in the position shown in Fig. 12, -by the weighted forked end of the lever, the lugs 74, will not pass backward under the bottom edge 62 of the lever 58, but the lugs 74, 75 will be engaged by the forked end 66 of lever 58, definitely limiting the outward movement of the extension in its return `cycle and causing the lugs to `move in a path which is not the reverse of their path previously described in extending the table.

After the lugs 74, 75 have engaged in the forked end 66 of lever 58, the lever 58 will pivot counter-clockwise and the frame members 68, 69 will drop downward until they are supported by the base of the slots 82, in the frame member 28, after which the extension may be pushed inward and the edges 92 of the extension will ,be slidablyreceived upon the shoulders y93 of framemembers 29and 30,the extension moving to the position shown in'Fig. 3. l

During the operations of sliding' the table extensions outward or inward, the extensions are caused to move in a direction parallel to the table top 22 by means of the frame members 68, 69, which are guided inthe slots'82, 83 of frame member 28 and by means of the dowel pins 78, 79 and blocks 76, V77..

The operation of the embodiment shown in Figs. 5 to 8 is substantiallythe same as that previously described, with the exception that the extensions 28, 24 are slidably supported upon the tops of the frame members `29 and 80, instead of upon rabbeted portions of these frame members. t

It will thus be observed that we have .invented-an improved construction of eXtenlsible tables, in which the extensions may be automatically movedto ythe extended posi- `tion .or to the folded position, by merely pushing or pulling upon the extension. In

moving the extension to the extended position, it is highly desirable that the extension be moved to a point beyond the edge of the table top, then leveled with the tabletop and then returned into abutting relation with `folded position, it is necessary only to pull the extension out slightly, after which it drops immediately to its lower position'to be slid in under the table top, the Vextension being supported in spaced relation to the table top by means engaging below the extension, so Vthat neither the extension `nor thel table -top can be marred kby the `normal operation of the device. It is highly improbable that anyone would pinchtlie fingers in opening an extensible table of the present construction, since it is necessary only to grasp the table at a point where there is no possibility of pinching, and it is unnecessary to simultaneously lift the top or to use the other hand for securing the extension in its elevated position, since the mechanismy automatically levels the extension with the table top and secures it in proper extended position.

The present device is thus capable of being extended lor folded, merelyv -by the use of one-hand and with the application lofa very slight force on the part of the operator.

While we have Aillustrated a preferred embodiment of our invention, many modifications may be made without departing from the spirit of the invention, and -we `do not A wish to be limited to the precise details'ofV construction set forth, but desire to avail ourselves -of all changes within the scope off `Aof a supporting frame with avtable top carried thereby, a movable top extension adapted to .be located adjacent the edge of said top to form an extension thereofor below sald top, a pair of guide rails iixedly secured toi said movable top extension, a guide member carried bysaid supporting frame, and guide mechanism consisting of a singleswitchvr lever carried by said extension for automatically guiding said extension` from a po-f sition below said top to a position where said extension forms a part of said top. n
